Beefed-up performance models get 225kW engines and much peppier performance, thanks to a more upmarket BMW cabin.

Mini has detailed the updated John Cooper Works versions of its Clubman wagon and Countryman crossover, which both get beefier performance amongst other upgrades.

Headlining the changes is what lies under the bonnet – a 225kW/450Nm 2.0-litre turbocharged four-cylinder petrol engine borrowed from the related BMW X2 M35i, the most powerful engine fitted to a production Mini.

In both models, the more powerful motor betters the outgoing cars by 55kW and 100Nm, and is hooked up to a new eight-speed Steptronic automatic transmission and 'All4' all-wheel drive.

The new Clubman JCW can accelerate from 0-100 in a blistering 4.9 seconds, while the Countryman JCW takes 5.1 seconds – a significant 1.4 and 1.5 seconds quicker than the previous iterations respectively.

Beyond the upgraded powertrain, the Clubman JCW and Countryman JCW get a new exhaust system, a petrol particulate filter compliant with the Euro 6d-TEMP emissions regulations, a mechanical differential lock for the front axle, new and larger JCW brakes, along with Matrix LED headlights and Union Jack LED tail-lights (Clubman JCW).

Speaking of the brakes, the front discs measure 360mm at the front and 330mm at the rear, with new four-piston calipers at the rear.

Australia

CarAdvice has contacted Mini's local arm regarding availability and timing of the new JCW Clubman and Countryman models for Australia, and is awaiting a response.
